Wait and see - I bet you’ll find him sat in the bowl like Lord Muck within days!
I agree with Sandy that there’s nothing like being outside for torts when it’s the right time of the year but when they are in tables they need light, UV, a temperature gradient with a heat spot so they can thermoregulate, areas to hide and dig down and a source of water and you seem to be doing the best you can with all that.
We’ll beg to differ on the substrate but I’d guess you can only go so deep because the base of the cage doesn’t look too big and it’d be falling out through the bars.
Keep posting. Be nice to see more of Petrie.
